MP3 CD
INFORMATION AND ADVICE
Empty CDs are not recognised and may damage the system.
The MP3 format, an abbreviation of MPEG 1.2 & 2.5 Audio Layer
3, is an audio compression standard which permits the recording of
several tens of music fi les on a single disc.
In order to be able to play a recorded CDR or CDRW, when
recording, the ISO 9660 level 1.2 or Joliet fi le format is
recommended.
If the disc is recorded in another format, it may not be played
correctly.
It is recommended that the same recording format is always
used for an individual disc, with as low a speed as possible
(4x maximum) for optimum sound quality.
In the particular case of a multi-session CD, the Joliet format is
recommended.
The audio system will only play fi les with the extension ".mp3" with
a sampling rate of 22.05 KHz or 44.1 KHz. No other type of fi le
(.wma, .mp4, .m3u...) can be played.
It is advisable to restrict fi le names to 20 characters without using
special characters (e.g. " ? ; ù) to avoid any playing or displaying
problems.
